Question
How do I plug a monitor into my computer?
Answer
The connector contains 10 standard signal pins and 3 coaxial pins. On the computer side, the pins are female but the coaxial connectors are male. The coaxial connectors carry the video signal split into red, green/gray, and blue; the standard signal pins carry four grounds, three "sense" pins used to communicate with the monitor, vertical sync, horizontal sync, and a composite sync signal.
